I do not know what type of silicone spray you used as most of this spray is recommended for rubber seals. Check your can and see what it is supposed to be used for as it may have "sealed" the rubber on your door and you will need something to penetrate the silicone over-spray.

I would recommend you visit an auto parts store or an RV store and let them look at the over-spray and the can that you used so they can recommend what product to use.

It is possible the door rubber needs to be lubricated as well but with a product that will protect it over the years. This is usually some type of silicone spray. Be sure whatever you buy shows a picture of it being used on rubber.

There are lots of temporary fixes but they may cause more problems so think about this before adding something else.

The following is a quote from a research site:

"Manufacturers of pure silicone spray oil unequivocally and blatantly recommend its use on rubber. Major manufacturers of treadmills and personal prophylactics (condoms) provide silicone oil as a lubricant accompanying their products."

" DO NOT USE SILICONE SPRAY ON ELECTRICAL CONNECTIONS, SWITCHES, RELAYS, ETC. There have been numerous reports that silicone spray can cause contact problems in switches, noted in multiple posts regarding automotive problems. There are other products that are designed to protect and waterproof electrical connections and should be used instead.

Do not use on any surface upon which you walk, sit, or lay as it will be slippery.

Do not use on painted surfaces... the paint sucks up the silicone and makes paint prep ever more onerous than it normally is. Paint will not stick to silicone, so always minimize overspray when using silicone near painted areas.

Do not use on any item that you have to handle, such as the outside of a gun, fishing rod, door handle, etc."
